Einstein's theory of relativity caused us to rethink the meaning of both space and time, concepts that had been taken for granted for centuries. The foundation of this revolution is the special theory of relativity, which Einstein published in 1905.The general theory of relativity, published in 1916, is really a theory of gravitation set in the foundations of the special theory; it also allows us to analyze the properties of frames of reference that are accelerating.
